Built for Fun, Designed to Learn. The PSIA Ski & Snowboard School youth programs at Grand Targhee, Powder Scouts & Mini Moose, have a new inventive & creative skiing zone to keep everyone on the slopes entertained and having fun. For kids we have built THE KIDS ZONE. This is an inventive way to teach children how to not only how to learn to ski but how to have fun while they're at it.
